I am trying to replace the seals. The seam is at the bottom of the window frame in the middle, on the inside there are two small holes on either side of the seam./ends. Are these for pins or screws, if so they are pretty corroded.
 
As Neil says. I found on mine that they had turned to dust. Aluminium spares can be bought from the refurbishment companies. The channel will be a U shape, probably. On mine, I too had corroded holes. The glass was reinserted and the whole frame filled with the black Sikaflex adhesive sealant that is made for windows / frames. The sealant came out the corrosion holes and was smoothed over, and the mastic around the frame chamfered into the glass. The have been very water tight since fitted, over 5 years now. I dismantled and cleaned the frames and glass but had the assembly done by a refurbishment company.

Who did you use BOB? Despite poking with a tiny screwdriver I cannot even see if they are Philips or slotted screws... they are pretty old from 1979. I am intending to keep her for 15 years as probably my last boat so she is worth a bit of investment and TLC!
 
There are a number of refurbishment companies but I used Identifying Ownership and have been very please with their service. There was an indication that the owner was retiring but the web site is up and running and still saying that they offer a refurbishment service.

OK spoken to Jean Pierre at Hadlow Marine who says my windows are not designed to take apart as mine are pressed onto a fish plate not screwed in. I only have one seam so would have to bend the frame to get the glass out so as suggested I a, leaving well alone, will cut the old seal out and Jean is advising I use Arbosil ten, zero,nine,six... sorry IPad not doing numbers at the moment! And Scapa three,five,zero,seven slash twelve to fit frame to boat! Good enough for me. Interesting he is not saying sikaflex as he used on yours BOB!
 
Thats good news because now you know and before any attempt to split the frames damaged them. With care I am pretty sure you will end up with a better sealed window than original and neater looking. Take the time to get the sealant out through any corroded holes in the frames so that they are sealed. Make sure the glass is secured in place first before totally filling the frame, say with blobs of sealant to glue in position while supported with shims of wood. Something like that.
